| Question: |
|
| Why must I turn off the power of my cellular phone/PHS? |
|
| Answer: |
|
Cellular and PHS phones do not merely receive radio waves when switched on,
they send them continually to inform the ground station of their position. These
radio waves are stronger than most people imagine and may have an adverse effect
on the aircraft's navigational systems.
Please, from the moment you board until after you deplane, avoid the use of electric
and electronic devices, and in particular, make sure to turn off your cellular/PHS
phones. |
